> SingleOutputStreamOperator<Long> dataStream =
> env.addSource(new
> DataGeneratorSource<>(RandomGenerator.longGenerator(1, 1000)))
> .returns(Long.class)
> .setParallelism(10)
> .slotSharingGroup("group1");
> DataStream<Long> sideOutput = dataStream.getSideOutput(new
> OutputTag<Long>("10") {});
> sideOutput.map(num -> num).setParallelism(10).slotSharingGroup("group1");
> dataStream.addSink(new
> DiscardingSink<>()).setParallelism(10).slotSharingGroup("group2");
